Application filed October 8, 1912, Serial No. 724,618. Renewed July 25, 1914. Serial No. 853,234.

To all whom it may concern:

lBe it known that I, SARAH M KEYTE, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certalnnew and useful Improvements in Ventilating-Fans, of. which the following is a specification. 1

This invention relates to ventilating fans, and the principal object of the invention is to provide a ventilating fan which may be mounted in the wall of a building and which will rotate thus causing fresh air to be continuously fed into the room and at the same time removing used air.

Another object of the invention is to provide an improved means of constructing the fan so thatit will be very strong and so that the fan may be used as an advertising means.

This invention is illustrated in the accompanying drawings, wherein Figure 1 1s a side elevation showing the fan in position. Fig. 2 15 a vertical sectional view showing the manner of mounting the fan. Fig. 3 is a fragmentary sectional view showing the mechanism for running the fan. Referring to the accompanying drawings. it will be seen that this invention is mounted in an opening 10 formed in the wall 11 of a building, the Wall being provided with a flue 12 leading from the opening 10 and provided at its outer end with suitable louvers 13. A second set of louvers 14 are secured to the outer face of the wall and extend across the upper portion of the opening 10 so that the fan will be protected from inur J l he fan is mounted in the opening 10 and comprises the shaft 15 which is mounted in suitable bearings 16. A sleeve 17 is rigidly mounted upon the shaft 15 and is provided with longitudinally extending ribs 18 to which the blades of the fan are secured. Each of these .blades comprises a pair of plates 19 which are secured upon opposite sides of the ribs 18 and for the major portion of their height are secured together. The outer portions of the plates are spread apart as clearly shown in Fig. 2 and have their edges bent inwardly to form tracks 20. Transparent sheets 21, are secured in these tracks and with the plates 19 form housings 22. Electric bulbs 23 are placed in the hous ings 22 so that the interior of the housings will be illuminated and thus the signs which will be displayed.

Specification of Letters Patent. Patentedliiar, 116, 1915b A motor 24 is mounted in the opening 10 and carries a gear wheel 25 upon its shaft which meshes With a larger gear wheel 26 rigidly secured to the shaft 15. This rotates the shaft thus causing the fan to operate and also causing the slip ring 27 rigidly mounted upon the shaft 15 to rotate so that the brushes 28 Wlll cause electricity to pass into the shaft thus giving power to illuminate the lamps 23. An ornamental lamp 29 is carried by a shaft having a beveled gear 30 meshing with a second beveled gear 31 carried by the shaft 15. A slip ring 32 and brushes 33 are provided so that when the shaft 15 rotates the lamp 29 will also be illuminated.

From the above description the operation of this device will be readilyamderstood, and it will be seenthat upon turning on the motor the shaft 15 will rotate thus causing the fan to rotate in the opening 10. Each blade of the fan as it passes into the opening carries a supply of fresh air through the opening and into the room and upon again passing through the openin upon its out ward turn carries a supply 0% used air which is sucked up through the line 12. The lights illuminate the signs and thus make it posslble for a person on the inside of a room or outside of the building to read the signs which are painted upon the transparent plates carried by the blades.

Having thus described the invention, what is claimed as new, is

1. A fan of the character described comprising a shaft, a sleeve rigidly mounted upon said shaft, ribs extending longitudinally along said sleeve, fan blades secured to said ribs, said blades being provided with outer end portions that flare in opposite directions transparent outer plates secured to the flared end portions of each pair of blades to provide end housings, and means forilluminating the housings.

2. A fan comprising a shaft, a sleeve rigidly secured to said shaft, fan blades secured to said sleeve each comprising a pair of sections having their major portions connected and their outer end portions liaring in diverging relation, transparent plates connecting the outer ends of each pair of sections to provide housings, illuminating means positioned in the housings beneath each of said transparent plates, and means for rotating said shaft to rotate said fan.

3. A wall having an opening formed therein and provided with a flue leading from said opening, a shaft extending longitudinally through the openin in-said wall,'fan blades extending from s id shaft and provided with pockets in their outer end' portions, transparent outer walls for the pockets, electric lampspositioned in said pockets, means for'supplying electricity to said shaft, and means for rotating said shaft.

4. A fan comprising a shaft, fan blades extending from said shaft and provided with pockets in their outer end portions,

said pockets having transparent outer walls, electric lamps mounted 1n said Kockets, a slip ringmounted upon said sha brushes contacting with said ring, a second shaft, an electric lamp carried by said second shaft, a slip ring mounted u on said second shaft, brushes contacting wit said secondslip ring,

means for rotating said first mentioned shaft, and means for conveying rotary motion from said first mentioned shaft to said second mentioned shaft.

-5. A combined ventilating and display fan comprising a shaft, blades projecting radially therefrom and arranged in pairs, thel pairs of blades bein connected throughout the major portions 0% their lengths and having their ends flared outwardly in opposite directions and provided with cover holders,

a' transparent cover for each pair of outwardly flared ends, said covers and ends forming housings, means for illuminating the housings, and means for rotating the shaft.

In testimon whereof I aflix my signature in presence 0 two witnesses.
